Description Nicola 2013-04-26 21:43:10 UTC
please copy this file on an android device:,mulaw.mkv

modify android tutorial 5 changing the media uri to:


and try to seek using the slider, often you'll hear the audio but the video will be frozen, if instead you change the state to pause before seek will work better,

if you play the file over http the seek work as expected,

any ideas? something in filesrc specific to android?

tested using gstreamer-1.0-sdk-android-arm-2013.04 too, similar results, since 1.0 actually does not ship ffmpeg I'm using amc for video decoding on a device with android 4.1 (I need ffmpeg for older android versions) and I can see errors like these:

gstamc.c:702:gst_amc_codec_dequeue_output_buffer Failed to call Java method
gststreamsynchronizer:c:357:gst_stream_synchronizer_sink_event:<streamsynchronizer0:sink2> Non-TIME segment: bytes

using ffmpeg for decoding (with 0.10 sdk) give similar seek issues
