can't find NDK camera and media native API symbols when linking libavdevice.a to libffmpeg.so

4 septembre 2018, par jianwen

I’m using NDK tools to build ffmpeg shared lib which will be used in my
android rtsp project.All needed components are compiled/linked as seperate
static libs, and at last these libs will be linked as a single shared lib.
Everything goes well except the last step. error happens when linking
libavdevice, all symbols in NDK camera and media can not be found, error

Converting Real Media with ffmpeg

22 avril 2018, par Eric Arenson

I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I’m able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like :

[avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

It may have something to do with the funky format of these Real Media files :

Does anyone have any tips on either how to find out what FFMpegX is doing to make the conversion work, or a better way to go about using ffmpeg to do this ?

Including the ffmpeg command (thank you to @Mondain for teaching me about the stream mapping !) and output :

FFMPEG HLS Multiple audio languages with var_stream_map - EXT-X-MEDIA:TYPE doesn't contain LANGUAGE

30 janvier 2020, par Moonsurfer_1

I have a question involving multiple audio languages on HLS with FFMPEG.

I’m currently using the following command to mux a transport stream with multiple audio languages into an HLS stream with a master playlist :

ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUTPUT_FOLDER/stream_%v_%d.ts" -var_stream_map "v:0,agroup:groupname a:0,agroup:groupname a:1,agroup:groupname a:2,agroup:groupname a:3,agroup:groupname" -master_pl_name master.m3u8 $FULL_OUTPUT_FOLDER/stream-%v.m3u8

The output of this command looks like this :

stream-3.m3u8



#EXT-X-STREAM-INF:BANDWIDTH=174900,CODECS="mp4a.40.2",AUDIO="group_groupname"

stream-4.m3u8

While this does seem to work with VLC, I need the EXT-X-MEDIA:TYPE tag to contain the LANGUAGE property. (the player I’m working with uses it to parse the audio tracks’ language) I can’t figure out how to do that based on the documentation I’ve found.

Could anyone help me with this ?

Thanks !
